I wanted to share a service I'm hosting, but didn't feel comfortable just leaving publicly accessible, even behind a reverse proxy. In the meantime I did not want to give access to my whole lan with a VPN, or redirect all internet traffic from a client thru my network. So the idea is to run a WireGuard instance on my OpenWRT router in a completely isolated zone (input, output and forward set to reject on firewall) and then forward a single port from the service host's. Client is android, so using WG Tunnel and split tunnel just for the relevant app should not impair client's network access. Initial tests seems to be ok, is there anything I may have overlooked? Please feel free to comment.
The connection between your Pangolin service (hosted outside your network) and your LAN is through a VPN. Essentially you’re creating a proxy that you can point your domain address at which isn’t your house's IP address. Plus then everything inside your network is still secure behind your VPN.
So you connect to Pangolin, and Pangolin routes the traffic to your network.
